Thanks to the nifty pedometer that Jared gave me (which, unlike the one I got a year or two ago, actually seems to function), I can say with certainty that the above number is exactly how many steps I took today. I decided to measure a typical Tuesday because that's the day that I spend a lot of time on my feet; we process our comics shipment that day, so there's a lot of loading, unloading, sorting, counting, processing, and preparing to be done. Add to that my usual daily morning and afternoon walks and you get the magic number of 26,347.
(To be fair, my last pedometer did work just fine until it hit 999,999; then, instead of rolling over to zero, it just quit working. I guess it had counted as many steps as it cared to count...)
